You don't need a gym or pricey fitness machines to get a great workout. Here Jackie Warner (www.jackiewarner.com), star of Bravo's fitness reality show "Work Out," and author of the new book "10 Pounds in 10 Days," demonstrates a close-to-wide squat. All you need is a flat surface and some way to demark a circle. A jump rope works just fine.

What to do: Place the jump rope in a circle around you. Stand within the circle, hands clasped together at chest level, squat down to sitting position, then jump up. Land with your legs now outside of the circle, lowering into a squat again.

Jump up again, this time landing with your feet inside the circle where you started. Repeat!
